To all whom it may concern:

Be it known that 1, WILLIAM L. MORROW,

a citizen of the United States, residing at Stockton, in the county of San Joaquin and State of California, have invented certain new and useful Improvements in Double Cyl-' inders for Gas-Engines; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,'reference being had to the accompanying drawings, and the characters of reference marked thereon, which form a part of this specification.

My invention relates gas or gasolene engines, and particularly to the cylinders thereof; and my object is to produce a double cylindersuch as Will perform the work'for which it is designed without the danger of explosion at the wrong time and also one which'will do the work easily and etfectually in less time and with less expense of energy than in the old-style engines. This object I accomplish by the peculiar and simple construction and adaptation of partsherein fully described, and particularly pointed out in the claims appended.

In the accompanying drawings sim lar characters of reference indicate corresponding parts in all the views.

Figure 1 is a longitudinal section of my improved cylinder. Fig. 2 is a side elevation of same. Fig. 3 is a longitudinal section of a modification thereof. Fig. 4 is a detail sectional view showing one of the exhaustvalves, and Fig. 5 is a bottom view of the same.

1 designates the main cylinder-shell open at both ends and provided with a solid partition-wall 2, which divides the cylinder'into two'distinct chambers 3 and 4. of said cylinder and on both sides are slots 5, lying parallel to each other -at diametrically opposite points of the cylinder.

6 is a piston working in the chamber 3, and 7 is a similar piston wor 8 8 are rods connected to the pistons 6 and 7 and extending through the slots 5 and along the sides of the cylinder 1 said rods extending across the end of the piston 6 and having inwardly-bent integral ends attached to the piston 7. I

9 is the stationary member of a spark-igniter located Within the chamber 3 and providedvwith a rod 9 ,-extending out through 13 is agrod adapted the stationary member 13 of a spark-igniter.

to improvements in words, the igniter of tance apart equal igniter-rods. and the exhaust-rods.

At each end ng in the chamber4.

thgside-of thecylinder-shell 1 just above, the. 1'0 8. 10 is an exhaust-valve within the chamber 3, connected with an exhaust-pipe 11=and provided .with' a rod 12, 'proj ecting througlh thg side of the cylinder-shell 1 just abovet e ro 8..--

to make contact with within thechamber 4, similar to the one within the chamber 3', and 14 is a rod connected to an exhaust-valve within the chamber 4, w

the chamber3. The rod similar to that in 13 extends through the shell loppositeto the side through which the rod 9 extends or on the same side as the rod '12-, and. the "rod 14 is on the same side as the rod 9*, or, in other one chamber and the exhaust of the other are on one side,

versa. 1

15 and 16 are small upwardly-projecting lugs on therod 8, said lugs having theirinner surfaces slightly curved 17 and 18 are similar lugs on therod .8. Said lugs are a disto the distance between the The main inlet-pipe is designated 19 and divided into twobranches 20 2 1, which lead, respectively, into two valve-Fboxes 22 23, the former being mounted on the chamber 3 and the'latter being mounted on the chamber 4. These valve-boxes '22 and 23. contain valves that control the inlet of the explosive mixture from the main inlet-pipe 19 into the chambers 3 and 4, and the movement of the valves within the valve-boxes 22 and 23 is effected by means of avalve-rod 24, that is conandvice nected to any suitable movable part of the engine. The exhaust-valveshown in Figs. 4 and 5 is'composed of a spherical casing 10, into which the exhaust-pipe 11 leads, and within the casing 10 is arranged a convex valve 10, that governs ports 10 in the bottom of the said casing 10. The valve 10 is carried on the rod 12, and the said rod is surrounded by a spiral spring 12, that tends to hold the valve in closed position.

The operation isas follows: After the machine is started the explosive mixture is admitted alternately into the chambers 3 and 4 by the movement of the valves in the valveboxes 22'and 23, and as the rods 8 8 are moved lengthwise the lug 18 comes in contact with the rod 13, which causes the sparker in the chamber 4 to explode the explosive mixture, which action drives the piston outward, and simultaneously the lug 17 comes in contact with the rod 12, which causes the exhaust within the chamber 3 to work, and the piston 7 being connected to the piston 6 by means of the rods 88*, pulls said lastnamed piston inward. When the-said piston has completed its stroke, the lug touches the exhaust-rod 14 and the lug 16 touches the rod 9, which causes an explosion inthe chamber 3, and the'piston 6 is forced outward and the piston 7 is pulled inward. Thus it will be seen that there is an alternating explosion and exhaust in the chambers 3 and 4, and thus I have produced a double cylinder for a gas-engine which after it is regulated will drive two pistons, thus making the engine just twice as powerful asfthe old style of engines. The rods 8 and 8, working in the slots 5, hold .the pistons 6 and 7 steady andprevent any untrue movement. In the double cylinders where one piston is usedthe flash or fiame of the explosion of one chamber sometimes escapes past the rings on the piston and causes an explosion in the other chamber at the wrong time, thus dis abling the engine.

3 shows a modification of my invention where the two chambers 3 and 4 are dissuch changes and modifications may be made in practice as *fairly fall within the scope of ma hi Having thus described my invention, what I claim as new and useful, andde'sire to se- 7 open at both ends, a solid cure -by Letters Patent, is

1. In a device of the kind described, the combination with a stationary maincylinder rtition-wall .in

' the of said cylinder dividing the same into two distinct chamberaa movable iston mounted in each chamber, piston-r0 s rigldly connected toboth pistons and extending along the outside of-the-cylinder, a plurality oflugs carried by each said red, a stationary ceases contact arranged in each chamber, a slidable contact-rod extending from each chamber through the side of the cylinder, an exhaust valve casing located in each chamber, a

'valveq'od extending from each chamber through the wall of the cylinder, a' valve carried by each said valve-rod, said slidable contact-rods and said valve-rods being adapted to contact with said lugs'whereby the rods will be moved to perform their respective functions by the longitudinal movement of the piston-rods.

2. The combination in a gas-engine of a main cylinder, a partition dividing said'cylinder into two distinct chambers, a piston arranged in each of said chambers, rods secured to each of the pistons and extending along the sides of the cylinder, a stationary electric contact located in each chamber, a

. movable contact-rod extending through the wall of each chamber, said contact-rods projecting at opposite sides of the cylinder anda lug carried by each said piston-rod, each lug beingadapted to contact with one of said contact-rods.

3. In a device of the kind described, the

combination of a cylinder, a partition-wall dividing said cylinder into two distinct chambers, a piston mounted in each of said chainbers, piston-rods connected to both saidpistons and extending along the sides of the cylinder, a sparking device arranged in each cylinder and comprising a stationary contact and a movablecontact, said movable con the same side of the cylinder as set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribin witnesses,
